Murrayfield Stadium is a rugby union stadium located in the Murrayfield area of Edinburgh, Scotland. The stadium is owned by the Scottish Rugby Union (SRU) who has its headquarters based at the stadium, and is the national stadium of the Scotland national rugby union team. With a seating capacity of 67,144, it is the largest stadium in Scotland, the fifth largest in the United Kingdom, and the twenty-second largest in Europe.

It officially opened on 21 March 1925 with a game between Scotland and England. The game was won by Scotland who came out victorious following a Grand Slam. The stadium hosts most of Scotland's home test matches and the Scottish Hydro Electric Cup final, as well as URC and European Rugby Champions Cup matches.

Although primarily a rugby union stadium, Murrayfield has in the past hosted American football, rugby league and association football matches, as well as numerous music concerts. Currently, the stadium is known as Scottish Gas Murrayfield Stadium for sponsorship reasons.

The SRU identified 19 acres of land at Murrayfield, purchasing this from Edinburgh Polo Club at Murrayfield, having raised money through debentures. A stand and three embankments were constructed, which took two years. Previous internationals had been played at Inverleith but it was not large enough to cope with the increasing number of spectators. Arthur Sellers was the stadium's first groundsman, having previously prepared the pitches at Inverleith. On 21 March 1925 England were the first team to visit Murrayfield, with 70,000 people watching Scotland beat them to win their first Five Nations Championship Grand Slam.

During the Second World War the ground at Murrayfield was offered to the nation and was taken over by the Royal Army Service Corps and used as a supply depot. During the war years the armed forces sports authorities managed to arrange two Scotland v. England services internationals each year, on a home-and-away basis. Scotland's home matches were played at Inverleith for the first two years with a return to Murrayfield in 1944 after that ground's derequisition.

Murrayfield's record attendance of 104,000 was set on 1 March 1975 when Scotland defeated Wales 12–10 during the 1975 Five Nations Championship. This attendance stood as a world record until 1999, and remains a European record. The East stand was built in 1983.

In October 1991 another debenture scheme was launched, to finance a more comprehensive redevelopment of the West Stand. The new West Stand was designed with a 48-metre cantilever roof. The old West Stand housed a museum, but this was not replaced and plans for a new visitor centre were shelved when the game turned professional. The first phase was completed in January 1993 with the new north and south stands opening. In February 1994 the centre section of the new West Stand opened. The work was carried out by Tilbury Douglas.

In 1994, Murrayfield completed a £50-million renovation where floodlights were installed for the first time.
